hey people i have a question on the turbo i am new to lexus and i was wondering what is a good turbo size,how much psi, and what type of fuel tuning is required. is the a point that i dont need to tune to for example below 8 psi or do you have to tune after install thanks
Well you can get the XSPower kit and use a Apexi Neo and still use your stock ecu and injectors but need a boost controller to keep you under wraps to about 7psi...The SRT kit is a complete kit that has everything you need included alot of IS guys run the SRT kit
